Personality Types Talks

In psychology, personality type refers to the psychological classification of individuals. In contrast to personality traits, the existence of personality types remains extremely controversial. Types are sometimes said to involve qualitative differences between people, whereas traits might be construed as quantitative differences. According to type theories, for example, introverts and extraverts are two fundamentally different categories of people. According to trait theories, introversion and extraversion are part of a continuous dimension, with many people in the middle.
